Preheat oven to 350°F. Line 2 baking sheets with parchment paper; set aside.
Prepare the crumbs: Combine ladyfinger crumbs, brown sugar, and coffee in a small bowl. Stir until combined. Mixture should have the texture of damp sand. Set aside.
Prepare the cookie dough: In the bowl of an electric mixer, on medium speed, beat together oil, cream cheese, and sugars until smooth.
Add espresso, egg, baking soda, salt, and vanilla. Beat until smooth and creamy.
Reduce mixer speed to low; add flour, one cup at a time, beating after each addition, until combined.
Use a medium cookie scoop (or a heaping tablespoon) to portion out dough. Roll into balls; then roll in prepared ladyfinger crumbs until fully coated. Place onto prepared baking sheets.
Bake for 10-11 minutes, until cookies are set.
